chore: trigger CI

it seems thta I don't have permission to rerun failed CI job. but
according to the job log, the failed test cases should not be affected
by my PR. pushing this commit to rerun the workflow and see whether the
CI will pass. I will remove this commit when it's OK to merge the PR.

see: https://github.com/rust-lang/rustup/actions/runs/16549617721/job/46802550142?pr=4429
